Treating Larch Wood Decking

Larch wood is a popular choice for decking due to its natural durability and hard-wearing surface. However, to preserve the wood’s appearance and extend its lifespan, proper maintenance is essential. In this article, we take a closer look at the best way to treat larch decking, with a particular focus on oil treatment using our effective exterior oil, DuroGrit.

Why Treat Your Larch Wood Decking?

Larch wood has a naturally high resin and oil content, making it more resistant to weather exposure compared to many other wood species. However, sun, rain, and changing temperatures will still affect the wood over time. Without proper treatment, this can lead to drying, cracking, and the development of a grey patina. A correct oil treatment helps protect the wood and preserves its natural colour for longer.

DuroGrit – The Right Oil for Larch Decking

When choosing an oil for treating larch decking, it is important to select one that protects against UV rays, moisture, and dirt. We recommend our exterior oil DuroGrit, which is suitable for all wood species and provides effective protection against changing weather conditions and strong UV exposure.

DuroGrit is available in a range of natural colours, giving you plenty of options to choose the shade that best complements your decking.

Preparation Before Oil Treatment

Before starting the treatment of your larch decking, it is essential to properly prepare the surface to ensure optimal oil absorption. Begin by removing dirt, algae, and old oil residues. We recommend using our Rubio Monocoat Outdoor Wood Soap, which cleans the surface thoroughly without harsh chemicals.

If the surface feels rough or has visible uneven areas, light sanding with sandpaper can help achieve a smooth finish. Make sure to remove all sanding dust and allow the wood to dry completely before applying oil.

How to Apply Oil to Larch Decking

Once the decking is clean and dry, you can begin the oil treatment. Apply the oil evenly using a wide brush, working in the direction of the wood grain. Work in smaller sections at a time and allow the oil to dry, which typically takes around 3 hours depending on weather conditions.

The frequency of oil treatment depends on the climate and how much the decking is used. Generally, oiling once a year is recommended for optimal protection, or as needed if the wood appears dry or dull.

To check whether your decking needs oil, sprinkle a few drops of water on the surface. If the water is quickly absorbed, it is time for a new treatment.

Maintenance Tips for Larch Wood Decking

To keep your larch decking looking great for many years, follow a few simple maintenance routines. Regular cleaning helps prevent algae and dirt from building up and creating stubborn stains. We recommend using our Rubio Monocoat Outdoor Wood Soap to clean the surface without damaging the wood. It is also advisable to use protective furniture pads under outdoor furniture to prevent unnecessary scratching.

Treating larch decking with oil is an effective way to maintain the wood’s durability and appearance. By choosing the right oil, preparing the surface properly, and following a regular maintenance routine, you can enjoy a beautiful and resilient deck for many years.

Oil treatment not only enhances the wood’s natural look but also protects it against weather and wear. With the right approach and a little consistency, your decking will look fresh and well-maintained season after season.
